'disabled' can probably be the default for a device that doesn't have a driver associated with it, once the runtime PM conversion is complete. That's what the late_initcall would do. Then if a driver is dynamically loaded for one of those devices, the hwmod code would just re-enable it. - Paul -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
